PHP has a specific function for various data types. In this case it is

is_int($var)

There are however other functions to check if the variable is an array, boolean, double, float, null, object, string, etc.

Thank you, so I don't need to create a function, PHP already has a function.

As you continue your journey you'll probably find that that's often the case. There are all sorts of hidden functions that I was re-writing myself because I didn't know they existed. Part of my continued learning is teaching myself how to be a better researcher to discover those things before creating them.
